So this post is to try and help out anyone stuck in the same situation I was earlier today!
My P3A was still on the stock FW it shipped with because I'd heard nothing but horror stories about the later ones, and 1.1.9 was working fine for me.
With the release of 1.4 I decided to upgrade. UAV and batteries went fine using the usual "bin file on the SD card" technique. Then I went to upgrade the RC, as it was complaining that it needed one. The upgrade using the DJI failed, I assume because the version on it was too old. So I put the 1.4 bin file on a thumb drive, and it wouldn't upgrade. The txt file it dropped said the installed version was the same or later than the upgrade file - which was obviously not the case.
A little head scratching later and I tried putting the 1.3.2 bin file on the thumb drive, given that it should have the same RC FW as the 1.4 one, and that worked great. So...not only does the 1.4 FW not _require_ an RC upgrade, it doesn't seem to even allow one. Odd!
